TSMC’s Arizona subsidiary recorded its first profit in the first half of 2025, four years after launching operations, according to a company financial statement.

The US unit, fully owned by TSMC, reported NT$4.5 billion (US$150 million) in net profit, reversing a loss of NT$4.3 billion (US$133 million) year-on-year.

TSMC, the world’s largest contract chipmaker, said the shift was due to higher market demand and increased production capacity.

The Arizona facility started high-volume production using 4-nanometer process technology in Q4 2024, with a second plant set to begin production soon on 3-nanometer technology.

Major customers include Apple, Nvidia, and AMD.

🧠 Food for thought

1️⃣ Manufacturing excellence can be successfully transferred when backed by substantial investment

TSMC’s Arizona facility demonstrates that semiconductor manufacturing expertise can be successfully relocated across geographies with the right approach.

The Arizona plant achieved semiconductor yields that are approximately 4% higher than TSMC’s facilities in Taiwan 2. This performance milestone is particularly significant given that yield rates directly impact profitability in semiconductor manufacturing.

The facility turned its first profit of NT$4.52 billion in the first half of 2025, compared to a NT$4.34 billion loss the previous year 1. This four-year journey to profitability occurred despite the facility requiring a massive $165 billion investment across multiple fabrication plants 3.

The success challenges common assumptions that moving advanced manufacturing from established hubs inevitably results in lower efficiency or longer learning curves.

TSMC’s approach involved transferring not just equipment but also sending engineers back to Taiwan for training, ensuring knowledge transfer was comprehensive rather than superficial 3.

2️⃣ Government support levels create stark differences in overseas expansion outcomes

The contrast between TSMC’s Arizona and Japan operations highlights how government support structures can determine expansion success.

While Arizona achieved profitability, TSMC’s Japan facility posted a NT$4.52 billion loss in the first half of 2025, widening from a NT$1.48 billion loss the previous year 1. Both facilities entered volume production around the same timeframe, yet their financial trajectories diverged significantly.
